This invention relates to new and useful improvements in cameras, andhas more particular reference to the application of a Cellophanereflector filter to the camera for color photography.

The invention contemplates a construction which may be used inconjunction with box cameras as well as other types of cameras, andmoving picture cameras.

Still further the invention proposes the provision of a frame with aDupont non-washable red Cellophane reflector fllter located at a 45angle to reflect rays of light and to allow other rays to pass through.

Still further the invention contemplates a novel construction by whichsaid frame is mounted within and held in position in the camera.

Another object of the invention resides in the association of certainshutters in the vicinity of the Cellophane reflector filter, by whichcertain rays may be shut out when desired.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

5 In Figs. 1 to 4, one form of the invention is disclosed in which astandard box camera i5 is shown provided with an improved removablecasing i6 supporting a frame I! with a Cellophane reflector filter I8,in accordance with this inven- 10 tion. The camera i5 includes the usualbox shaped housing i9 having an openable back 20 through which thecasing I6 may be engaged into position and removed from position whendesired. The casing l6 includes a pair of side walls 2| and 22 held inrelatively spaced positions with rods 23 mounted between these walls.With this construction the casing i6 is open at least at the top and atthe back. At the front it is closed and provided with an aperture 24through which the light from the lens and shutter mechanism may pass.

A partition wall 25 is mounted across the bottom portions of the sidewalls 2! and 22 and divides off a bottom compartment 26. Support 25means for a bottom supply spool of film 21 is located within thecompartment 25. The spool 21 is turnably supported by several supportpins 28 and a leaf spring 29 urging the spool against the pins 28. Thedot and dash lines 30 schemati- 30 cally indicate the film coming offthe supply spool 21. This film is shown extended across the rods 23, andconnects with the top receiving spool 3!. This top receiving spool 3| isturnably mounted within the casing it. It is urged against support pins32 by a leaf spring 33.

With the above construction a section 30 of the film 30 extends acrossthe back of the camera, and another section 30 extends across the top ofthe camera. The frame ll is mounted diagonally across the casing I6 atan angle of so that the light entering the camera, and schematicallyillustrated by the dot and dash lines 34, strikes the reflector filteri8. Some of this light 45 is reflected upwards against the film section30".

as indicated by the dot and dash lines 34. Some of the light passesthrough the reflector filter it, as indicated by the line 34 and strikesthe fllm section 30.

It is proposed that the filter l8 be of Dupont film which is then readyfor use, as a master positive for duplicate printing.

The frame it is releasably held in position. There are several side lugs35 which are mounted on the partition 25 and which engage the front andback bottom edges of the frame ll. Leaf springs 3.5 also on thepartition 25 urge the frame ll upwards. The top of the frame. it has aconcave portion 3? which engages one of the rods 23. Thus the frame H isreleasably held in position. It may be removed by manually forcing itdownwards to compress the leaf springs 36 and then moving" the top ofthe'frame ll laterally to disengage it from the rod 23. The frame isthen free to be pulled out from the casing It. The camera is providedwith the usual depressible knob 3% which may be connected with the keyopening 39 in the top spool 38 in the usual way so that the film may bewound thereon. In other respects the camera is standard.

In Figs. 5 to 11 another form of the invention has been disclosed whichis very similar to the prior form, distinguishing merely in the factthat a pair of flexible shutters 3d and iii have been provided, whichmay be individually engaged across the casing it of the camera to shieldofi the top and the back sections of the film, when this is desired. Theshutter at is wound up and located within a hollow drum .42 mounted inthe compartment 25. This drum has a slot 43 through which the shutterAll extends. A track system 44 is mounted on the side walls of thecasing iii to guide the shutter 40 along the back of the camera. Cables45 are connected with the sides of the shutter and are extended upwardsover drums 46 mounted on a shaft 41 which is rotative in the top portionof the casing, I5. The shutter 4! is also wound up and housed within ahollow tubular casing 42 having a, slit 43 in one side through which itpasses. Tracks 44' are moimted upon the side walls of the casing I5 toguide the shutter 4| across the top, section of the film. Cables 45' areconnected with the sides of the shutter and engage over drums 46'mounted on a shaft 41' mounted across the sidewall of the casing 16.

Another shaft 48 is located between the shafts 41 and 41' and is tumablyand slidably mounted.

One end of the shaft 48 engages in a bearing 49 mounted on one wall ofthe casing IS. The other end of the shaft 48 is provided with a.coupling 50 coactable with the stem 5! of a turning device having aturning knob 52. The shaft 48 is provided with a gear 53 andfrusto-conical wheels 54 and 55 mounted on opposite sides of the gear53. The shaft 41' is provided with a gear 56 which is adapted to meshwith the gear 53 and which is normally held from turning by a springoperated pawl 51. This pawl'has a control finger 58 which is located inthe vicinity of the conical shaped wheel 54.

The shaft 41 is also provided with a gear 59 which is held from turningby a spring pressed pawl 60. The pawl 60' is provided with a finger 8|disposed in the path of motion of the conical shaped wheel 55. Eachshutter 40, 4| is mounted and wound on a shaft 63 which is connectedwith a spring 54 mounted betweenthe shaft and the casing of the shutter,and acting normally to retract the shutter.

The knob 52 may be pressed inwards to conmeet the coupling 50, 5|. Thenthe shaft 48' may be shifted inwards or outwards to engage the gear 53with the gear 59 or with the gear 55. When these gears are engaged theconical shaped aseineo wheels 55 or 543 engage and move the fingers hior 58 to release the gear 59 or 65. Then the knob 52 may be turned towind up the cables 45 or 45' to extend the shutters fiber ii, or to letout the shutters so that the springs as rewind the shutters.

The construction is such that the shutter dd may be extended across thebacker the casing to block off the back section of the film, or theshutter 4i may be extended across the top of the casing to block ad thetop section of the filin, or both shutters may be extended to block offboth sections of the film. In other respects this form of the inventionis similar to the previous form.

In this form of the invention a filter 55 is shown to be attached infront of the lens 68. This filter consists of a holder 6? and a filtersheet 68 made of Cellophane or like material, in any desired color. Whenthis filter it is made of a colorless transparent Cellophane sheet, itwill roduce a partially polarized efiect.

In Fig. 12 another form is disclosed in which a standard motion picturemachine it is shown provided with a removable casing it mounted directlybehind the shutter and lens ii of the camera. This casing 86 supportsthe frame it having the Cellophane reflector filter iii. The film '12 ofthe camera is guided over the top and the back of the casing I6. Withthis construction two sections of the film are exposed, due to directrays through the filter reflector i8, and the other for the reflectedrays. The camera 10 is standard in all respects except that the ratio ofthe sprockets must be changed so that the film I! advances two frames ata time to prevent double exposure to the top and back sections of thefilm. The upper film section is printed (positive) and dyed red. Theback section is printed on wash-oft relief film and synchronizedtogether with the red film. This prints blue on to the red film which isthen ready for use as a master positive for duplicate printing.

In Fig. 13 two separate films l3 and '14 are illustrated to besynchronously connected by the gear 15 and 16, respectively, so thatfilm 14 may be exposed to the direct rays through the filter it, whilefilm 13 is exposed to the reflected rays.

It is to be understood that the above principle may be used inconnection with two or more color box cameras, of any design.
